The claimed particle classifier is utilized to separate precious metalsfrom alluviums in placer mining. The plurality of curved bars functionsas riffles to entrap heavy precious metals and conduct the said heavyprecious metals into the slit and consequently into the plurality ofsmall troughs located beneath the slit. The claimed particle classifieris operated along with a flow of stream water, which deposits particlesand sediment into the slit and the plurality of small troughs. Theclaimed particle classifier may be operated along with a flow of waterfrom any source other than streams.

CLAIM The ornamental design for a particle classifier, as shown anddescribed.
